Serial N01 513,543.

-The invention relates to awning arms adapted to maintain the awning fabric of a roller awning fora store front and the like in open or extended position, the awning arms also being adapted to be folded up against the vertical wall of the store front when the awning is not in use, "as when the I awning fabricis wound up upon it roller.

More particularly, the inventionrelates to an adjustable type of awning arm which may be made in standard sizes under production methods, and which may be adjusted at the time the awning is erected so that the outer end ofthe awning arm may be located at a certain specified or predetermined place, regardless of the places at which it may be required to attach the brackets to a wall for mounting the arm thereon,

Thus, it i necessary that all awning and awning arm parts be located at a certain predetermined distance above a sidewalk so as to provide sufficient clearance thereunder to r permit pedestriansito walk beneath the awning without the liability of injury by accide'ntallystriking an awning part.

Moreover, storefronts which are to be I shaded by an awning, differ in arrangement and dimensions from each other, and are not uniform in providing suitable places for attaching brackets on which awning arms may be mounted. r And finally, having due regardfor the required clearance,- it is most desirable to i which the mounting brackets for the awning maintain the awning in extended position as low as possible in order that a maximum shading of the store front may be obtained, regardless of the location of the places at arm are attached to the front wall.

Accordingly, it is an object of the presentfinvention to provide an awning arm which may be attached to or mountedon a vertical wall, within desired limits, sub-- stantially at any place above the ground level,-'the outer end of the awning arm being adapted to be located at a fixed predetermined distance above the ground level to 'obtain'the necessary clearance for and vention to provide an awning arm comprising a lever system forming a so-calledlazy tong type awning arm in which oneimember of the lever system is adjustable as to effective length, and flexible throughout a portion of its length so as to permit the same to be adjustablyconnected to one of the awning arm mounting brackets for varying the location of the outer end of the awning arm in extended position without vary ing, changing, or modifying the length of any of the other links of the lever system.

And finally, an object of the present invention is to provide means for adjusting a lazy tong type awning arm, which adjustment means will not prevent the awning arm from being folded in a compact manner against the vertical wall upon which the awning is rolled up.

These and other objects may be attained by a construction, preferred embodiments of which are shown in the accompanying drawings, which may be stated in general mounted, when the awning is terms as including a compound lever com- I I of its adjustment, in dot-dash lines in extended position at the lower limit of its adjustment, and in 'dot-dot-dash lines in fold: ed or retracted positions; L I L Fig. 2 is a verticalsection through one form of bracket on which the awning arm is adjustably mounted; v i

Fig. 8 is a view similar to Fig. 2, showing the bracket of Fig. 2 in an adjusted position Fig. 4 is a perspective view of the com- I ponent parts of the bracket shown in Figs.

1, 2 and and Fig. 5 1s a sectional view similar to 2, showing a modified form of bracket and V flexible member.

Similar numerals refer to similar parts throughout the drawings. V A single improved ad ustable awnmg arm generally indicated at 5 is shown in Fig.

1, it being understood that two or more are required to be used in connection with every roller awning installation.

An awning roller '6 is supported on suitable brackets 7, which are attached to" the vertical wallindicated by the line 8 above that portion of the wall which is desired to be shaded by the awning. Suitablewinding devices (not shown) are provided for the awning roller 6 for winding up or un winding the awning fabric 9 upon the roller 6. r

' Brackets 10 and 11, for supporting each adjustable-awning arm 5, are attached to the wall 8 at available places located below the roller 6.-

The "awning arm 5 preferably comprises a lever system composed of links forming an irregular lazy tong which includes an outwardly extending arm or link .12 which is secured at its outer end 13 to a rod 14 to which the outer edge of the awning fabric 9 15 attached.

' bar .link 17 and the short link 18 pivoted at The link 15 formed of twin channel bars is pivoted at .16 to the link 12 and the compound lever formed by the twin channel 19 to the link 17, is likewise pivoted at its outer end to the inner end of the link 12,

; as shownx-at 20. A lever arm or link 21 is pivoted at its inner end to the wall bracket '11, extends outwardly .and upwardly from the wall 8 and is pivoted at its criter onto the inner end of the link 15 as shown at 22. 7 An intermediate portion of the link 17 is pivotedgat .23 teen intermediate portion of the link '21;

v(As t-hue far described, the irregular lazy tong awning arm is-of an old and well known type, and my invention is directed particularly to the means by which the end of the link :18 is Iadjustably attached to the wall bliaekfet 10. 1}

In the preferred form of .my invention, shown in Figs. 1 to 4, inclusive, the wall bracket lO includes a base plate 24; prcferably attached to the .wall 8 by screws A pair of ears 126 provided with apertures 27 extend outwardly from the lower end ofthe base plate 24, and a pair of ears 28 provided with a pluralityof sets of spacedapertures 29 extend outwardly from the upper end of the base plate .24. second plate or chain 7 engaging member 30 is pivotally mounted at its ower end on a shaft 31 journale'd the apertures 27 of the ears 26. A pair of ears 32 provided with apertures 33 extend outwardly from the plateBO intermediate the ends thereof.

A flexible member 3a composed of pivoted 7 links 34 forming a link chain is pivotally connected at to the inner end of the short link 18 of the compound lever. A detachable bolt 36 journaled in the apertures 33 connects the flexible member34= to the-plate 30 of the wall bracket lllby sele'ctive engagebe'selectively journaled any, setof the v plurality of sets of aperturesi29 formed in the ears 28. V

Referring to .Fig. 1,, the adjustable awning arm 5 is shown in full lines in extended position at the upper limit of its adjustment wher in the outer edge of the awning is located as indicated at B after having been unroll-ed from a folded position shown in dot-dash lines wherein the outer edge of the awning is l-ocated'as indicated at .A.i .llhe adjustable awning arm is likewise shewnin Fig. 1 in dot-dash lines at alower limit of adjustment wherein the location ofthe-outer edge oftheawning is indicated at BQ,

Iuone physical embodiment of ture shown in Fig. l, the point B is approximately and one-half feet outward from '1;

the point A and approximately two and onehalf feet below thepoint A,' while the point B is located approximately six feet outward froniand six feet below the point A. i

It is understood that thepoint B or 13 is '3" the determining position for the awning since 1t must be located at adistan ceabove a sidewalk ;so as to provide sufficient clearance thereunder to .perrnit'pedestrians to walk beneath the awning, and the brackets i 7, l0 and 11 must be attachedto the wall 8 at available places, after wliiclrtheawning arm mounting may be adjusted as required;

it is clear that the adjustment of the posi tion of the awning arm 5 between the upper and lower lmnts shown'in Fig.1, is determined by the e'ffective'length' of the flexible member 845. which determines the location of the point with relation to the wall 8.

The effective length ofthe fiexiblemember Bainay be adjusted or varied by selectively engaging any one of the links 34 thereof by the-bolt 36, and in one physicalembodiment of the invention, an adjustment from one link to the next adjacentlink will result Iii;

the strucv ion in a vertical adjustment of theouteredge of the awning, approximately three and onehalf inches.

possible adjustable positions, the inner and outer of which are shown, respectively, in Figs. 2 and 3. In one physical embodiment of the invention, an adjustment of the bolt 38 from one set of apertures torthe next adjacent set of apertures results in a variation of one and one-quarter inches of the vertical position of the outer edge of the awning.

In the modified form of my invention shown inFig. 5, the wall bracket 10a includes a base portion 24a preferably attached to the wall 8 by screws 25. A'pair of ears 32a extend outwardly from the base plate portion 24m, and areprovided with apertures 33a in which a bolt 36a is removably journaled. I

Theflexible member 34a is pivotally connected at 350. to the inner end of the short link 18 of the compound lever. Adjustment of the eflective length ofthe flexible member 34a is accomplished by adjusting the location of the collar 39 secured to the flexible member 34a and abutted against the bolt 36a and the ear 4O projecting from the outer surface of the base plate portion 24a.

Accordingly, the location of the outer end of an adjustable awning arm may be varied by shifting the position of the collar 39 on the flexible cable member 34a.

Of course it is understood, that when an adjustable awning arm involving the present invention has beeuinstalled, and the adjusted location of the various parts has been made, the'surplus end of the flexible member 34 or 3440 may be cut off, the arrangement being permanent once the various parts have been adjusted to the required positions.
